1. Shuck the clams by prying each open with a knife. Cut the clam from the shell. Slit the skin of the clam's siphon (neck) and pull off and discard the tough skin. Scrub the bottom shells and discard the tops.

2. Place a clam in each bottom shell and place the shells on a baking sheet.

3. Combine the butter, onion, bell pepper, parsley, lemon juice, and Worcestershire sauce in a small bowl and mix well.

4. Preheat the broiler.

5. Spoon about 1 teaspoon of the butter mixture into each clam. Sprinkle the crumbled bacon on top.

6. Broil for 3 minutes, until the butter is bubbling. Serve hot.
